Problems solved by technology

[0005] Based on the traditional oil-water separation method, there are disadvantages such as long time-consuming, high energy consumption, complex equipment requirements, etc., and the single function makes it impossible to realize the dual functions of oil-water separation and antibiotic catalytic degradation at the same time. To explore and develop a more effective simultaneous dual-function material is of great importance

Abstract

The invention belongs to the technical field of nano-functional omentum material preparation technology, and relates to a preparation method of a cobalt oxide-loaded omentum bifunctional material; specific steps: dissolving cobalt chloride in ethanol solution to obtain cobalt chloride ethanol with a certain concentration The solution was ultrasonically oscillated to fully dissolve; then, after the stainless steel mesh was properly cut, it was placed in acetone and ethanol solutions for ultrasonic treatment; then the stainless steel mesh treated in step (2) was immersed in the chlorinated In the cobalt ethanol solution, take out the stainless steel net and burn it under the outer flame of the alcohol blowtorch to obtain the cobalt oxide loaded omentum bifunctional material; the cobalt chloride used in the present invention is oxidized into tricobalt tetroxide with catalytic function, which can realize catalytic performance , and increased the roughness of the omentum surface, while realizing the dual functions of catalysis and oil-water separation, with excellent comprehensive performance.

Description

technical field [0001] The invention relates to a preparation method of a cobalt oxide-loaded omentum dual-function material, which is a dual-function material with catalytic performance and oil-water separation performance, and belongs to the technical field of nano-functional omentum material preparation technology. Background technique [0002] With the frequent occurrence of marine oil spill accidents and the massive discharge of industrial oily sewage, the environmental problems caused by oil pollution are becoming more and more serious. And with the abuse of antibiotics, as many as 24 kinds of antibiotic pollution in seawater have been detected. [0003] The traditional preparation methods of nano-membrane materials for oil-water separation include chemical oxidation method, hydrothermal method, etc., and the processing steps are cumbersome, including a series of complex steps such as high-temperature calcination, high-temperature hydrothermal, dissolution and dispersi...
